Abstract
BACKGROUND: The association between hepatitis B and metabolic syndrome (MetS) has not been well described. Overall epidemiologic evidences for this association have suggested conflicting results. The aim this study was to determine the association between hepatitis B infection and MetS using large U.S. population database, the Third National Health and Nutrition Examination Survey. METHODS: Individuals aged ≥18 years were included in this study. MetS was defined according to the Third Report of the National Cholesterol Education Program Adult Treatment Panel guideline. The chronic hepatitis B was defined as the presence of hepatitis B surface antigen. The presence of hepatitis B core antibody with/without surface antibody, in the absence of surface antigen, was considered as past exposure to hepatitis B. To represent national estimates, weighted frequencies for chronic hepatitis B and past exposure to hepatitis B are reported. Multivariate logistic regression analysis accounting for age, gender, race, smoking and alcohol status was conducted to identify the independent predictor(s) of MetS. RESULTS: This study cohort consisted of total population of 593,594 with chronic hepatitis B and 7,280,620 with past exposure to hepatitis B. Prevalence of MetS among included study cohort was 25.7%. Inverse association was observed between MetS and chronic hepatitis B (adjusted odds ratio, 0.32; 95% confidence interval, 0.12-0.84). Among individual components of MetS, waist circumference was inversely associated with chronic hepatitis B (adjusted odds ratio, 0.31; 95% confidence interval, 0.14-0.71). No significant association was noted between past exposure to hepatitis B and MetS or its individual components. CONCLUSIONS: In this study, the authors noted significant inverse association between MetS and chronic hepatitis B.
